Question about Cyberhome CH-DVD 300 DVD Player
The exact same thing happened to mine several days ago. I opened mine up, noted that two of the capacitors on the power supply are a bit puffed up, and tested the power supply's 12V and 5V outputs. The 12 Volt output is fine, but the 5 Volt output is only putting out 2 Volts. In short, all of the capacitors on the power supply are made by the same company (Jenpo) and apparently these capacitors were made using the stolen but incomplete formula for manufacturing capacitors much more cheaply. That "capacitor scandal" has cost electronics manufacturers millions. In any event, this would explain why Walmart blew out these Cyberhome CH-DVD 300 players for such a cheap price. Obviously all of the capacitors on the power supply will eventually fail. I have already experienced similar capacitor related problems with a few computer motherboards and other electronics equipment which I bought in the early to mid 2000's. I am contacting Cyberhome to see if they will send me a replacement power supply to go in my CH-DVD 300.

If you have any ability with a soldering iron, you could replace the caps yourself and get the player up and running a lot faster than Cyberhome will ever help you.
I did it just today on my dead one using caps I bought from Allied Electronics. The obvious culprit was the 2200uF 10V cap, but I replaced them all anyway. Total cost was about $3. The caps were part of an order I placed for parts on another project I am working on. I figured, what the heck, for a couple more bucks I'll get these caps and try replacing them myself before I throw the thing away. It worked!
As for getting a replacement PS from Cyberhome, what if it has the same garbage jenpo caps on it?

The red "off" power off indicater on my Cyber Home 300 was lighted & I turned the power with the remote, however, the red indicator went off but the green "power on" indicator did not come on. All attempts to get either the red or green indicator failed. I opened the box and found that the DC to DC converter that supplies power to the DVD drive unit was 12V & 2.5V. I figured that the voltages should be 12V & 5 VDC. Bridged another 2200uf capacitor across the existing 2200uf capacitor for the "5 VDC" supply and the voltage increased to 4.0VDC. I assume that the original 2200uf 5V supply capacitor has leakage so I plan to remove the "bad" capacitor which I expect will fix the problem. I wonder if Cyber Home will provide a replacement board??

First you don't unplug it from the wall just hit the button and shut it off you probably blew a fuse
